To all whom 'it may concern: v sitely disposed side of the support 9,these Be it known that I, HENRY OLivER Cornia, a citizen of the UnitedStates, and a resident of Terre Haute, in the county of Vigo and Stateof Indiana, have invented a new and Improved Scafold, of which thefollow-l ing is a full, clear, and exact description.

My invention relates to scaffolds, and it has for its object to providea scaffold which can be quickly erected or dismantled and one which whenin position will afford a strong and ready support.

Still other objects of the invention will appear in the followingcomplete description.

In this specification I will describe the preferred form of myinvention, but it will be understood that I do not limit myself thereto,as I consider myself entitled to all forms and embodiments of theinvention which may be held to fall within the scope of the appendedclaim.

Reference is to be had to the accompanying drawings, forming a part ofthis specilieation, in which similar characters of ref'- erence indicatecorresponding parts in all the figures, in which- Figure 1 is aperspective view of my invention, as erected; Fig. 2 is an elevation ofone of the standards Fig. 3 is a sectional side elevation of thesameg'Fig. 4 is a plan view of the base; Fig. 5 is a fragmentary viewshowing the arrangement of the sleeves with the brackets thereonsupported on a standard; Fig. 6 is a plan view of the sleeve with thebracket; Fig. 7 is a plan view of the socket frame; and Fig. 8 is a planview of the brace. i

By referring to the drawings, it will be seen that standards 1 areprovided, these standards 1 having a series of transverse orifices 2therein, the standards 1 also each having an orifice 3 disposed neartheir base. The standards 1, when erected, have their bases inserted insockets 4 which are riveted or otherwise secured toa base member 5.'Ihese base members 5 are triangular in shape and each has two of itssides 6, extended beyond the third side 7 the socket member 4 beingsecured to this third side 7 Base braces 8 extend from the sides of thebase members 5 upwardly toward the standard, the upper terminals of thebase braces 8 having secured to them a support 9, the support 9 beingdisposed around three of the four sides of the standard 1. There areorifices in the oppoorices being in alinement with the orifices 3 in thestandard, when the standard is in-` serted in the socket member 4, andinthese orifices is inserted a pin 10, which is adapted to hold thestandard firmly on the base member 5. Brackets 11 are provided, throughwhich the standards 1 are disposed, the brackets 11 having oppositelydisposed teeth 12, which are adapted for engaging the surfaces of thestandards to hold the brackets at a predetermined height on thestandards.

The rear terminals 13 of the brackets 11 are bent downwardly, so thatthe teeth 12, which are in close proximity thereto will retain a betterhold on the standard. Opposite the rear terminals 13 of the brackets 11are supports 14, for a beam, said supports being integral with thebrackets. It will be seen that when any weight is carried by thesiipports 14, they will tip the brackets so that the teeth 12 willobtain a firm hold on-the standard 1 and prevent the brackets 11 fromslipping downwardly.

I propose to use a number of standards, and when the standards areerected on the base members 5 and are disposed apart, as shown in Fig. 1of the drawings, a beam 15 is provided. the beam being disposed on thesupports 14. In order to obtain additional support for the beam 15,braces 16 are roA vided, these braces 16 having yokes 1 at one end andyokes 18 at the other, the arms of the yoke 17 being adapted to bedisposed at either side of the standard 1, there being orifices 19 inthe said arms ofthe yoke 17,

`and through these orifices is disposed a pin 20, the pin 20 alsopassing through one of the orifices 2 in the standard. By this means thebrace 16 is held firmly to the standard, and it is also held to the beamby providing one of the arms 21 of the yoke 18 with a roughened innerface, en oppos'ite arm 22 having a threaded orifice in which meshes ascrew 23, the screw 23 being adaptfastened to the brace 16 by cords 25,and the in 10 is connected with one of the base graces 8 by means of acord 26. y

By constructing the base members 5 as has been described, and bysupport-ing the standards 1 on the socket members 4, with the sides 6 ofthe base members 5 extendin beyond the socket members in o positelrections, a very firm support is o tained, While at the same time thestandard may be quickly removed from the base member 5, in order thatthe scaffold may be shipped. It is also possible to quickly remove thebeams 15, the brackets 11 and the braces 16 from the standards, so thatall the parts may be quickly packed for transportatlon.

Having thus described my invention, I.

claim as new and desire to secure by Letters Patent In a scaffold,standards, bases having sockets` inlwhich the standards are disposedrespectively, supports for the standards disposed at a dlstance abovethe sockets, the supportsbemg disposed in close proximity to two sldesof the standards respectively, braces which connect the sup orts for thestandards with the bases, there ing orifices in the sides of thesupports for the standards which are in allncment with orifices 1nthestandards, and pins disposed in the orlfices by which the standards areheld above the bases respectively.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

HENRY OLIVER COFFIN.
